Chemical Resistance of Polypropylene and Polyethylene

Generally speaking the chemical resistance of polypropylene and polyethylene is considered superior to that of met-als. They are unaffected by most inorganic acids alkalis and aqueous solutions which rapidly corrode metals although some concentrated acids and oxidizing agents can attack them especially at elevated temperatures.

What is Polyethylene Plastic (with pictures)

Polyethylene plastic is an inexpensive plastic material that is chemically resistant and can be very durable. Polyethylene plastic comes in a low density form and a high density form. The low density form was discovered first followed a few years later by the high density form. Low density polyethylene plastic (LDPE) came about in 1933 when it
